Sohil Kshirsagar is an American software entrepreneur and engineer who is the co-founder and chief executive officer of Tusk, an artificial intelligence company that develops AI agents for automated software testing and bug fixing. Founded in 2023 alongside Marcel Tan, Tusk emerged from the Y Combinator startup accelerator and is headquartered in San Francisco, California. Before founding Tusk, Kshirsagar studied at the University of California, Berkeley, where he was involved with Sigma Eta Pi, a collegiate entrepreneurship fraternity. Outside of his professional work, Kshirsagar is known for co-creating a Super Bowl prop bets application with Sohan Kshirsagar, a side project that has attracted more than 20,000 annual users since its launch in 2020.

Early Life and Education

Sohil Kshirsagar grew up in the United States and attended the University of California, Berkeley. While at Berkeley, he became involved with Sigma Eta Pi (SEP), a collegiate entrepreneurship fraternity on campus. In September 2019, Kshirsagar delivered a special presentation at SEP's first recruitment event of the academic year, held at the International House on the Berkeley campus. His involvement with the entrepreneurship fraternity reflected an early interest in startup culture and business development during his undergraduate years.

During his time at Berkeley, Kshirsagar also began working on personal software projects. In early 2020, he and Sohan Kshirsagar developed the first version of a Super Bowl prop bets application, which took approximately three weeks to build. The application was originally conceived as a way for friends to place informal bets on ancillary Super Bowl events, such as the color of the Gatorade dumped on the winning coach.

Career

Early Projects and the Super Bowl Prop Bets App

Beginning in 2020, Kshirsagar and Sohan Kshirsagar launched a Super Bowl prop bets application as a side project. The application allowed users to place informal wagers on various non-game events during the Super Bowl, such as the Gatorade color, halftime show details, and other ancillary occurrences. The first version of the application took three weeks to develop.

The app grew substantially over subsequent years. By February 2025, Kshirsagar reported that more than 20,000 people were using the application each February during Super Bowl season. In a LinkedIn post, Kshirsagar noted that users returned to the platform annually, describing it as a recurring tradition: "Every February since 2020, Sohan Kshirsagar and I dust off our Super Bowl Prop Bets app." In a separate post from February 2025, Kshirsagar elaborated on the annual ritual, writing that he and Sohan Kshirsagar would "chug a few cold brews and crack our knuckles to make sure our Prop Bets app is ready to handle a large influx of users for the Super Bowl." Kshirsagar indicated that the project had begun as a personal desire to bet on Super Bowl prop events with friends and had organically grown into a product with a sizable recurring user base over six years.

Founding Tusk

In 2023, Kshirsagar co-founded Tusk alongside Marcel Tan. The company developed an AI agent designed to automate the generation of unit and integration tests for software code. Tusk was accepted into Y Combinator, one of the technology industry's most prominent startup accelerators, and was based in San Francisco, California. As of its Y Combinator listing, Tusk had four employees.

Tusk's core product positioned itself within the growing market for AI-powered developer tools. The company's AI agent was designed to assist software development teams by automating aspects of the testing process that are traditionally time-consuming for human engineers. The platform aimed to generate both unit tests, which verify the behavior of individual code components, and integration tests, which ensure that different parts of a software system work together correctly.

Product Development and Bug Fixing Capabilities

By mid-2024, Tusk had expanded its product capabilities beyond test generation to include automated bug fixing. According to coverage by HireTop, a technology industry publication, Tusk's AI coding agent could automate the process of identifying and resolving customer-reported bugs in software products. The publication described the tool as a means of "boosting developer productivity" and "ensuring high-quality software products" by automating tasks that would otherwise require manual developer intervention.

The expansion into bug fixing represented a broadening of Tusk's value proposition from purely testing-focused automation to a more comprehensive developer productivity platform. The AI agent's ability to fix customer bugs was positioned as a way to reduce the time developers spent on maintenance tasks, allowing them to focus on new feature development and other higher-priority work.

Thought Leadership and Technical Writing

Under Kshirsagar's leadership, Tusk published technical content aimed at the software development community. In October 2025, the company published an article titled "The Case for Comment-Driven Development" on its official website. The piece argued that writing more comments in code makes developers more effective and described how teams using AI-native development workflows could employ what Tusk termed "Comment Driven Development" to produce more maintainable code.

The concept of Comment Driven Development reflected Tusk's broader philosophy about the intersection of human developer practices and AI-assisted coding. The approach suggested that well-commented code served as better input for AI agents, creating a feedback loop where human-written documentation improved the quality of AI-generated code and tests.

Engagement with AI Developer Tools Ecosystem

Kshirsagar has been an active participant in the broader AI developer tools ecosystem. In 2025, he engaged with the open-source community around AI coding tools, including filing a feature request on GitHub for Anthropic's Claude Code product. The feature request, submitted to the Claude Code repository, proposed improvements to environment selection and visibility when starting the AI coding assistant from the Slack messaging platform.

This engagement with competing and complementary AI developer tools suggested Kshirsagar's active involvement in understanding the broader landscape of AI-assisted software development, even beyond Tusk's own product offerings. His participation in open-source discussions and feature requests indicated a hands-on technical approach to understanding the tools and workflows that developers use alongside or in conjunction with Tusk's platform.

Personal Life

Kshirsagar is based in San Francisco, California, where Tusk is headquartered. He maintains a collaborative relationship with Sohan Kshirsagar, with whom he co-developed and continues to maintain the Super Bowl prop bets application. The two have worked together on the application annually since 2020, treating the Super Bowl season as an occasion to update and prepare the app for its yearly surge in users.

Kshirsagar maintains a professional presence on LinkedIn, where he shares updates about both Tusk and his side projects.
